'Inverse opal' structure improves thin-film solar cells

(Phys.org) —Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D "photonic crystals" to absorb more sunlight than conventional ...

A new world record for solar cell efficiency

In a remarkable feat, scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin film solar cells on flexible polymer foils with a new record efficiency of 20.4 percent for ...

Researchers develop printable lasers

(Phys.org)—A way of printing lasers using everyday inkjet technology has been created by scientists. The development has a wide range of possible applications, ranging from biomedical testing to laser arrays for displays.

Safer nanoparticles spotlight tumors, deliver drugs

(PhysOrg.com) -- Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule flakes of ...

Scientists break record for thinnest light-absorber

Stanford University scientists have created the thinnest, most efficient absorber of visible light on record. The nanosize structure, thousands of times thinner than an ordinary sheet of paper, could lower the cost and improve ...

A cheaper way to produce nickel ferrite thin films

(Phys.org)—Researchers from North Carolina State University and the Georgia Institute of Technology have demonstrated a less-expensive way to create textured nickel ferrite (NFO) ceramic thin films, which can easily be ...
